For most panels, the calibration data is stored on the LED modules. To read the correct calibration data into the receiver card, power-cycle the panel once. The correct calibration data will be loaded into the receiver card when the LED panel is powered on.

However, there is some variation between panels and systems. A general recommendation is as follows: If the calibration does not recover in 15sec, power cycle the LED panel. If it still does not recover, check the instructions specific for your control system and LED panel.
